A26 urban motorway in Linz has received the last court approval. Now they can tender this section. Works are supposed to start at the end of next year and be completed in 2022.

The whole 4.7 kilometer project won't be completed until 2031 though. That's 16 years of construction. I guess the main reason to slow it down is to spread the large cost over a longer period of time. The project cost is € 645 million, or € 137 million per kilometer.

I'm surprised that Austria and Germany have probably the longest construction times in the world for highways.
They usually are very efficient countries in other fields.

Not S26? Strange, they seem not to like A-numbers anymore.

Austria is not Germany

this seems to be a big project but in real this are three ones:

1. build the urgent need Donau - bridge (that it is numbered as motorway does not matter, we need this f**king bridge)

2. build the tunnel to get the the traffic out of the west part of the city
(there is no place for construction = long time to build)

3. replace the existing bridge on the south, the existing one should be at end of life about 2030

and not forget to mention the other motorway the A7 will be refurbished in the same time because it is needed, they have to be careful not to complete deadlock the city in the next years, means construction general in small pieces, not because of money, because of keep traffic flow

@A7 expand / repair this donau bridge will start 2018, wont disrupt the traffic because the lanes will be doubled with 2 new bypass bridges:
existing:


future:


first will be the bypasses build, phase 2 will be the existing bridge free of traffic and get a complete repair, after this the bypass bridges are used for the exit traffic with both exits north and south of the bridge and the main bridge for transit traffic, this split will create a much better flow through this actual bottle neck

i don't understand now. 4 or 16 years for 4,7 km section from Unionstrasse (A7 south) to Donau bridge?

shouldn't 16 years be term for whole motorway including northern section from Donau bridge to A7 northern connection at Linz Urfahr?

Or in more exact numbers from the ASFINAG page (http://www.asfinag.at/verkehrssicher...z-hummelhof/):

06/2018 - 12/2022: Build the new Danube bridge, so around 4.5 years for that. This will enable a fully functional additional Danube crossing.

Preparatory work that has partially already started is mostly in pipes, cables, wires, ....

It is a rather special bridge, because:

- It is suspended only on the hills/banks of the Danube, on both sides.
- The ramps for the exit t will be in tunnels.

As it is maybe not the easiest to imagine, here a visualisation (I really don't know why the Danube is depicted as so brown... Maybe to indicate that it was polluted already before the new bridge is built...):





01/2023 - 12/2028: 6 years for building the tunnel under the mountain; as Christian says, this will make the road fully functional as a western route through the city, just not fully grade-separated.

01/2029 - 12/2031: 3 years to build a motorway-grade bridge over the Westbahn railway.

So yes, it is a really long time. Not due to being slow or inefficient in construction, but rather because it is, as pointed out already before, split into three sections that are done in series, due to funding issues. It is a very expensive piece of road :-)

You can see a video of the new road at https://www.youtube.com/watch?v=ynhJg7r5sA0

A26 will begin at A7 south and end just north of Danube! There won't be any connection to A7 north at Urfahr!

sooner there was project with whole connection, so full length tunnel Pöstlingberg (cca 3 km) and connecting to A7 at Urfahr. is that idea quit?

Quote:
Ende 2010 gab die Asfinag bekannt, dass sie aus finanziellen Gründen keinen Vollausbau als Autobahn mehr plant. Nach Gesprächen zwischen Bund, Land Oberösterreich und Stadt Linz einigte man sich im Jänner 2011 auf einen Kompromiss, wonach nur der Südteil vom Knoten Hummelhof bis zur Donaubrücke gebaut wird.
Die Gesetzesänderung, mit der der Nordabschnitt der A 26 aus dem Bundesstraßengesetz gestrichen wurde, trat am 30. Juli 2011 in Kraft.
Asfinag said in late 2010 that a "full Autobahn" is too expensive. They agreed in January 2011 that only the southern section will be built. The northern extension was officially (modification of the law) canceled on 30th July 2011.

i think that needs a little bit of background additional information

20 years ago the company asfinag (100% owned from the country) was created because the motorways are really bad and always funding problems, with the 100% owner the company gets cheap credits, to fund it the company collects on its own toll, and simple it works, the last 20 years motorways get better and better

because of this structure and the austrian federal system local politicans try to get needed roads to a motorway status that the company has to build and pay for it, you see this in periods that a lot of roads are added to the projected network and some years later removed/downgraded, same for this A26 for example, the actual part has major benefits in a local view but there is the point to collect the NW of upper austria to the motorway network which has actual no connection and has to pass the city to reach the motorway, the north removed part wont have real global benefits for the motorway network = canceled

Last week, I was around the Poysdorf area, and took the chance to visit some of the A5 construction site. As a reminder, this is a the section from Schrick to Poysbrunn, see the map below, and the official ASFINAG website at http://www.asfinag.at/verkehrssicher...g-drasenhofen/. Opening is planned for December 2017


- First interesting observation, Google Maps has updated their imagery, images are now from May 2017, opposed to until recently from November 2006 (!) (also Google Earth only had the old ones).
You can nicely see the alignment at https://www.google.at/maps/@48.58900...!3m1!1e3?hl=de, and more towards the north.
OSM Link as well: http://www.openstreetmap.org/#map=13/48.5839/16.6690

Now to the pictures, part 1/4

- First pictures are along the newly re-aligned national road B7, between Schrick and the new interchange Wilfersdorf Süd, which also connects to the Mistelbach bypass, opened last year; see https://www.google.at/maps/@48.54440...!3m1!1e3?hl=de







-- Crossing the A5 at the interchange


-- And in the opposite direction:



- A bit northern of this, pictures from bridge for the agricultural road at https://www.google.at/maps/@48.56638...!3m1!1e3?hl=de

-- Loking northwards:




--Looking southwards:





- A bit more nothern, from east of the bridge at https://www.google.at/maps/@48.57327...!3m1!1e3?hl=de

A5 Schrick-Poysdorf, part 2/4

- Further, at the Wilfersdorf Nord interchange: https://www.google.at/maps/@48.60219...!3m1!1e3?hl=de
Here, the two roundabouts that will connect the B7 road with the ramps are already in place, and can cause a minor delay.

-- On the B7








-- Looking eastwards









-- Looking westwards





-- Various ramps

A5 Schrick-Poysdorf, part 3/4

- At the new interchange in Walterskirchen: https://www.google.at/maps/@48.65289...!3m1!1e3?hl=de

-- Approaching the bridge from the east




-- The western ramps


-- View from the bridge

-- First southwards





-- Then northwards



--- Then on the bridge itself:

A5 Schrick-Poysdorf, part 4/4
- Crossing of the A5 with the L3052 north of Walterskirchen: https://www.google.at/maps/@48.67559...!3m1!1e3?hl=de

-- Eastwards




-- Westwards






-- On the bridge, workers were painting the rails


- And a bit west of that, crossing with the L22: https://www.google.at/maps/@48.68215...!3m1!1e3?hl=de


-- Westwards


-- Eastwards



- Finally, at the end of the section, just at the L3050: https://www.google.at/maps/@48.70886...!3m1!1e3?hl=de
It seems that while there is still a bit of carriageway built from L23 (Poysbrunner Straße) northwards, parallel to the existing B7, I am not sure how this will be used, they would still need to build a connection from B7 to the motorway. I think this will happen, they wouldn't just use the Poysbrunn interchange a bit southern of that, and leave this part as a stump. It looks similar to the current alignment in Schrick, where just after the interchange the motorway transforms to the B7.

-- Looking southwards, one can see a bit of asphalt


-- Northwards the area is leveled, but it is only used for storage etc.


-- They asphalted a previously unpaved track parallel to B7, connecting L3050 and L23, currently as a deviation for L23, which is closed just before meeting B7 at the future Poysbrunn interchange, see https://www.google.at/maps/@48.70917...!3m1!1e3?hl=de
I could imagine that in the final configuration, they are actually closing the intersection of L3050 with B7, the layout of the newly asphalted road connecting to the existing L3050 at https://www.google.at/maps/@48.71314...!3m1!1e3?hl=de would indicate that this is the new primary relation. This would remove one at-grade intersection of B7, it would be thus preferable.

Short news regarding the S7 Fürstenfelder Schnellstrasse, which will connect from the A2 in Styria via Burgenland to border with Hungary Heiligenkreuz, near Szentgotthard), and there be continued towards Körmend:



Preparatory roadwork (besides widening a bridge on A2, which has been branded as being parts of the S7 works weeks before provincial elections....) was supposed to start this spring, but then the approval regarding water rights was overturned; now, this approval is granted by the next instance; see http://www.asfinag.at/ueber-uns/news...chnellstrasse/ for the text in German.

ASFINAG wants to tender the major construction works still this year, no update on the plan to open this motorway by 2023 has been yet given (https://www.asfinag.at/verkehrssiche...chnellstrasse/)

Not really a good idea. Rather concrete on top of asphalt. But better just concrete or asphalt, not both.
